Gene for B-cell development factor might be involved in multiple sclerosis

28.10.2005


A gene involved in B-cell development might play a role in multiple sclerosis. The results of a large study published today in the open access journal BMC Neurology reveal that multiple sclerosis (MS) patients are more likely to carry two specific genetic variations in the Early B-cell factor gene (EBF-1), than healthy individuals.



These variations – or polymorphisms - could play a causative role in MS or be located near other polymorphisms that do play a causative role in the disorder. As such, they could be used as genetic markers for MS.

Alfonso Martinez and colleagues from the Hospital Clinico San Carlos, in Madrid, Spain, who carried out the research, suggest that EBF-1 might be involved in MS due to its role in axonal damage. "Axonal damage is a hallmark for multiple sclerosis," write the authors, and EBF is involved in the expression of proteins essential for axonal pathfinding. How axonal damage occurs in MS, however, is not well understood.


In their study, Martinez et al. compared the occurrence of a polymorphism at a single point in the DNA sequence of the gene EBF-1 – also called a single nucleotide polymorphism (SNP) - in 356 patients diagnosed with MS and 540 healthy individuals acting as controls. Both groups consisted of white Spanish individuals. The authors also compared the variants of a microsatellite – a highly variable, short stretch of non-coding DNA within the EBF-1 gene - in the two groups.

Their results show that patients with MS are more likely to carry the base adenine in the SNP analysed, than controls (p=0.02). In addition, one specific version (allele) of the microsatellite was more frequently found in MS patients than in controls (p=0.08). The authors confirmed this finding with a Transmission Disequilibrium Test: a study of the transmission rate of the allele in 53 patients and their parents, which showed that the allele was more likely to be present in both patients and their parents than other alleles.

MS is one of the most common neurological diseases in the Western world. It has traditionally been considered an autoimmune disorder of the central nervous system, and it is likely to be the result of a complex combination of genetic and environmental factors.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
